Application filed May 28, 1918. Serial No. 770,816.

To all whom it may concern.-

Be it known that I, Aunm M, (Jones, ol' Hyracuse, in the county of Onondaga and State of New York, have invented a certain new and useful 'Intcrnal-Combiilstion-Engine Governor, of which the following is a specification.

This invention has for its object the production of an internal combustion engine particularly simple in. construction and highly eflicient in use and it consists in the combinations and construw tions hereinafter set forth and claimed. In describing this invention reference is 15, had to the accompanying drawings in which like characters designate corresponding parts in all of the views,

Figure 1 is a plan view of my governor,

the contiguous portion of the intake pipe we and the cylinders of the internal (:OIllbllS tion engine being also shown.

Fig. it is horizontal cross-sectional view of this governoix r Fig. 3 is an elevation looking upwardly '25 in Fig. 2, the cap, holding the valve in position, being removed.

' Fig, 4 is a perspective view of the valve.

This internal combustion engine governor comprises generally a casing adapted to be 80 connectedin the intake pipe of the engine between the carburetor and the engine cyl inders or the intake yoke, and a normally open suction controlled valve movable in l the casing in a direction contrary to the 53 flowof, the gases through the casing Where- ,by ;tlie\valve when it approaches or nearly reaches its closed position, isrelieved of the suction created by the vacuum in the eingine cylinder-s92,"

1 designates the cylinders, and 2 the yoke of the intake pipe, which yoke is connected :to the cylinders in the usual manner; '3is l the cttrb'iireter connected to the intake pipe section 4, The enginemay be of-any type and include anynpmber of cylinders. iThe intake oke carburetor may also be of any desirab e :forin, size and construction. ,5 --,is' the,=,casing of the governor, the casing having'in'let and outlet passages 6 and; 7

which when the casing is cmillectecl in the intake pipe, communicate respectivelv with thecarbureter and the engine cylinders or intake yoke 2. In the "illustrated embodiinent of'iny invention the passages 6 and 7 5 0 arranged at an; angle to each other and t outlat. passage includes a circumferential groove orchannel 8 extending around and opening into the passage 6, and a valve 9 is arranged to move crosswise of the'outlet 7 in a direction contrary to the flow of the gas, (as indicated by the arrows) and into the inlet (3. Hence, the valve 9 when in its closed position is relieved: of the suction created by the vacuum in the engine cylinder and is free to move toward its open position. Owing to the groove 8 the action of the suction on the valve is equal on all sides of the valve so that there is no tendency to bind on the part of the valve.

As here shown, the valve 9 reciprocates in a passage 10 alined with the passage section 6 and located on the opposite side of the passage 7 to that on which the passage (3 is located, the passages 6 and 10 opening through opposite sides of the casing. The outer end of the passage 10 is closed by a cap 11. The valve is moved by the suction against the influence of a spring'lQ located in the passage 10 and bearing against op- -posing shoulders 13 and H provided respectively on the casing and on the valve 9;

The passage 6 and valve 9 are shaped to efiect a gradual shutting off of the gas by the suction as the valve 9 approaches or enters the passage '6, and the valve approaches its closed position the peripheral surface of its advance end is opposed to and of less diameter than the opposing sun face of theinlet passage; and one of said opposing surfaces is formed tapered. As here illustrated, the advance end of the valve 9 is tapered as at 9 valve at 9 provides the governor with a passage connecting opposite sides of the valve, whereby" the communication. between The tapering of the the inlet and-exhaust passages is mainto the tapered end of the valve 9, said valve will gradually lint oil the outlet passa e 7 and hence "will be gradually relievedx of the suction, ;whereupon the valve spring will again move the valve toward its open posilion, so that in use the valve is constantly fluctuatingtoward and from its closed position. and, owing to the fact that the valve is relieved f the suction, and to the lfart that the passage 7 extends circuinl'ercntially around the inlet passage (i, said valve is very sensitive and ellicient in its operation.

The governor of this application is of the same type as that shown in my pending application Sr. No. 723,502 liled Oct. 2, 1912, ()ne of the chief dill'ereni'zes between the governors is that in the governor of this application the movement of the valve in a direction contrary to the flow of gas instead of in the direction of the lion otgas as in the ropendingr application.

\Vhat I claim is: v

1. An internal combustion engine gov ernor comprising a casing; adapted to be winner-ted in the intake pipe oi the engine and having! inlei and outlet passages, and a normally open suction rontrollial valve arranged to move toward the inlet passage into position to cut oil the outlet passage, which is ermine-(le lo the engine cylinders. said valve being niovahh in a direction contrary to the lion oi the gas through the. miss-ages whereby the valve is relieved of the suction when in its closed position, the advance end of the valve being designed to enter the inlet passage and being of smaller diameter than the contiguous portion oi the inlet passage and loosely fitting the same, substantially as and for the purpose set forth.

.2. An. internal combustion engine governor comprising a :asing adapted to be connected in the intake pipe of the engine and having inlet and outlet passages, and a normally open suction controlled valve arranged to move toward the inlet passage which is connected to the engine carburetor, said valve being movable. in a. ilirectio'i'i con trary to the flow of gases through the passages whereby the valve is relieved of the suction when in its closed position, the advance end of the valve beingdesigncd to enter the inlet passage and the peripheral surface of such advance end being opposed to the inner circumferential surface of the contiguous portion of the inlet passage and one of said opposing surfaces being tapered whereby a gradual-shutting oil of the gases and suction is effected, substantially as and.

for the purpose described.

3. An internal combustion engine governor comprising a casing adapted to be connected in the intake pipe ofathc engine ernor comprisins a casing adaptedto be connected in the intakcpipe of the engine and having inlet and outlet passages arranged at an angle to each other, the former being in communication with the carburetor, and the latter with the engine cylinders, the casing being also formed with a valve passage alincd with the inlet passage and located on the opposite side of the out let passage to that on which the inlet passage is located, and a valve movable in the valve passage across the outlet into the inlet whereby the valve is ji e lieved of the in fluence of the suction who in its closed po sition, the advance end 01' .thovalvc being of slightly less (115mm; than the portion of, the. inlet 'ia'ssage in which said-advance end enters, substantially as and the purpose specified. r

5. An internal combustion engine gov ernor comprising a casing for connectibilkQO in an intake pipeof the engine, the casing having inlet and outlet passages, and a normally open suction controlled valve arranged to move toward the inlet passage into a position to cut off the outlet passage which is connected to the engine cylinder, the valve being movable in a direction contrary to the flow of gas through the passages-wl'iereby the valve is relieved of the suction when in its closed position, and the governor being formed with a passage for maintaining communication between the inlet and outlet passages as -the valveapproaches its closed position. In testimony whereof, I have hereunto 105 signed my name in the presence of; two attesting witnesses, at Syracuse,'N. Y., in the county of Onondaga, in the State of New" York, this 8th day of May, 1913.-
